Description

Technical Field

[0001] This utility model relates to the field of plant cultivation equipment technology, and in particular to a constant temperature incubator for plant cultivation. Background Technology

[0002] Incubators are core equipment in plant seedling cultivation, tissue culture, and germplasm resource preservation, providing a stable and controllable temperature and light environment for plant growth. Most existing incubators are one-piece chamber structures with multiple internal support racks sharing the same temperature control system. This makes it impossible to set differentiated cultivation temperatures for plants on different layers, limiting their applicability to a single plant variety.

[0003] Some incubators with layered temperature control have poor isolation between layers, allowing airflow and temperature interference between the upper and lower temperature zones, resulting in low actual temperature control accuracy. Furthermore, the support plates are often simple drawer-type sliding structures without effective support after being pulled out, making them prone to sagging, tilting, or falling off when heavy culture containers are placed on them, posing a safety risk. In addition, existing support plates and guide rails are mostly fixed connections, making disassembly and cleaning inconvenient; the openings where the guide rails slide into the tank lack protection, allowing moisture, nutrient solution drips, or dust to easily enter the gaps during the culture process, leading to jamming and corrosion over time, shortening the equipment's lifespan.

[0008] Preferably, the blower assembly includes a first air chamber formed in the inner wall interlayer of one side of the housing. The inner wall of the housing has several parallel elongated air outlets with vertically downward openings that are connected to the first air chamber. The first air chambers of each layer of the blower assembly are connected to the main blower duct through a first branch pipe, and an electric proportional valve is provided on the first branch pipe. The main blower duct is vertically arranged in the inner wall interlayer of the housing, and its upper end is sealed to the output end of the air box fixed on the upper surface of the housing.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Unless otherwise defined, the technical or scientific terms used in this utility model shall have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "first," "second," and similar terms used in this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figures 1 to 11 As shown, a constant temperature incubator for plant cultivation includes a vertical rectangular box body 1. A door 2 is hinged to the front of the box body 1, and a sealing strip 10 is installed on the inner side of the door 2. A transparent observation window can be embedded in the middle, balancing the sealing of the cavity with ease of observation. Several layers of support units 3 are arranged parallel to each other from top to bottom inside the cavity of the box body 1. A partition plate 4 is horizontally arranged between adjacent layers of support units 3. The partition plate 4 is a heat-insulating solid plate structure and divides the internal cavity of the box body 1 into multiple independent upper and lower cultivation chambers, blocking airflow and temperature transfer between the chambers.

[0023] The inner wall of the box 1 is provided with multiple sets of temperature control units 5 corresponding to each of the cultivation chambers. Each set of temperature control units 5 includes a blowing assembly 51 and a return air assembly 52 located on the inner walls of the left and right sides of the box 1. The blowing assembly 51 outputs temperature-controlled airflow into the chamber, and the return air assembly 52 recovers the airflow in the chamber. The two work together to form a horizontal circulating air path in the corresponding cultivation chamber to ensure uniform temperature in the chamber.

[0024] Each layer of the load-bearing unit 3 includes a load-bearing plate 31, a pull-out assembly 32, and a support assembly 33. The pull-out assembly 32 enables the horizontal pulling out of the load-bearing plate 31, and the support assembly 33 enhances the structural stability in the pulled-out state.

[0025] The pull-out assembly 32 includes T-shaped guide rails 321 symmetrically arranged on the inner walls of the left and right sides of the housing 1. Both T-shaped guide rails 321 are arranged parallel to the front-to-back depth direction of the housing 1. T-shaped sliding plates 322 are slidably fitted inside the T-shaped guide rails 321. The cross-section of the T-shaped sliding plates 322 is perfectly adapted to the T-shaped guide rails 321, allowing them to slide back and forth along the guide rails without coming off from the side. The inner surface of the T-shaped sliding plates 322 facing the center of the housing has a horizontally extending groove 323. The left and right sides of the support plate 31 are respectively embedded in the grooves 323 of the T-shaped sliding plates 322 and are fixed relative to the T-shaped sliding plates 322 by the fixing assembly 7, so that the support plate 31 can be pulled out synchronously with the T-shaped sliding plates 322.

[0026] Two sets of fixing components 7 are symmetrically arranged on the left and right sides of the upper surface of the support plate 31 near the door 2. The fixing components 7 include guide grooves 71 formed on the upper surface of the support plate 31. The extension direction of the guide grooves 71 is perpendicular to the length direction of the T-shaped guide rail 321 (i.e., extending along the left and right direction of the box). A slider 72 is slidably disposed in the guide groove 71. The slider 72 has a rectangular cross-section and is clearance-fitted with the inner wall of the guide groove 71 to ensure smooth sliding without shaking.

[0027] A fixing post 73 is vertically fixed on the side surface of the slider 72 facing the T-shaped slide plate 322. A fixing hole 324 adapted to the size of the fixing post 73 is opened on the bottom surface of the groove 323 of the corresponding side T-shaped slide plate 322. The end of the fixing post 73 passes through the side wall of the guide groove 71 and extends into the fixing hole 324 to realize the locking and limiting of the bearing plate 31 and the T-shaped slide plate 322.

[0028] A return spring 74 is provided between the side surface of the slider 72 facing away from the fixed post 73 and the side wall of the guide groove 71. The return spring 74 is arranged along the extension direction of the guide groove 71, with one end fixedly connected to the slider 72 and the other end fixedly connected to the side wall of the guide groove 71. A baffle 75 is vertically fixed to the upper part of the slider 72 near the return spring 74. A placement groove 76 adapted to the baffle 75 is opened on the corresponding side wall of the guide groove 71. The baffle 75 can slide completely into the placement groove 76 as the slider 72 slides. A protrusion 77 is vertically fixed to the upper surface of the slider 72. The operator can drive the slider 72 to move along the guide groove 71 by moving the protrusion 77.

[0029] When the return spring 74 is in its natural state, the slider 72, under the action of the spring force, adheres to the side of the T-shaped slide plate 322, and the fixing post 73 is inserted into the fixing hole 324, keeping the support plate and the slide plate locked together. At this time, the baffle 75 extends along with the slider 72, precisely blocking the upper opening of the guide groove 71, preventing water vapor, nutrient solution dripping, or dust from entering the groove during the cultivation process. When it is necessary to disassemble the support plate 31, push the protrusion 77 inward to compress the return spring 74, causing the fixing post 73 to exit from the fixing hole 324, and the support plate 31 can be horizontally pulled out of the slide groove 323. Disassembly and assembly require no tools and are easy to operate.

[0030] The support assembly 33 includes telescopic rods 331 symmetrically arranged on the inner walls of the left and right sides of the box 1. The telescopic rods 331 are located above the corresponding support plates 31 and do not occupy the plant cultivation space. The upper end of the telescopic rod 331 is a fixed end, which is hinged to the inner wall of the box 1 through a first hinge pin 332; the lower end of the telescopic rod 331 is a free end, which is hinged to the side of the upper surface of the corresponding T-shaped slide plate 322 near the box door 2 through a second hinge pin 333.

[0031] When the T-shaped slide plate 322 retracts inward along the T-shaped guide rail 321, the telescopic rod 331 shortens and rotates upward, retracting into the top of the chamber; when the T-shaped slide plate 322 slides outward, the telescopic rod 331 extends and rotates downward, forming a triangular support structure with the T-shaped slide plate 322 and the inner wall of the box 1, effectively bearing the weight of the front end of the bearing plate, preventing the front end of the bearing plate 31 from drooping and tilting after being pulled out, thus improving the load-bearing capacity and operational safety.

[0032] The air blowing assembly 51 is located in the interlayer of the inner wall of one side of the box body 1, including a first air chamber 511. The inner side wall of the box body 1 has several parallel elongated air blowing ports 512. The openings of the air blowing ports 512 are vertically downward and connected to the first air chamber 511, so that the airflow blows downward along the side wall of the chamber, forming a wall-mounted air path, avoiding direct blowing on the plant and causing damage.

[0033] Each air chamber 511 of the air blowing assembly 51 is connected to the main air blowing duct 514 via a first branch pipe 513. An electric proportional valve 515 is installed on the first branch pipe 513 to independently adjust the airflow volume of the corresponding layer. The main air blowing duct 514 is vertically installed in the inner wall interlayer of the housing 1, and its upper end is sealed to the output end of the air box 6 fixedly installed on the upper surface of the housing 1. Several first heating wires 516 are evenly arranged on the inner wall of the first air chamber 511 to heat the airflow and precisely control the outlet air temperature.

[0034] The return air assembly 52 and the blowing assembly 51 are symmetrically arranged on the inner wall of the other side of the housing 1, including a second air chamber 521 opened in the inner wall interlayer. Several parallel elongated return air inlets 522 are opened on the inner wall of the housing 1. The return air inlets 522 and the blowing inlets 512 correspond in structure and size. The openings are also vertically downward and connected to the second air chamber 521.

[0035] Each layer of the return air assembly 52 has a second air chamber 521 connected to the main return air duct 524 via a second branch pipe 523. The second branch pipe 523 is also equipped with an electric proportional valve 515. The main return air duct 524 is parallel to the main blowing air duct 514, and its upper end is sealed to the input end of the air box 6, forming a closed-loop circulating air path. Several second heating wires are evenly distributed on the inner wall of the second air chamber 521, which can supplement the temperature of the return air, further reducing the temperature difference within the chamber and improving temperature control accuracy.

[0036] The air box 6 has a built-in circulating fan and can be equipped with a refrigeration module (such as a semiconductor refrigeration unit) to achieve bidirectional temperature control for heating and cooling, meeting the cultivation needs of a wide temperature range. Through independent electric proportional valves 515 and heating wire control for each layer, independent temperature adjustment of each cultivation chamber can be achieved to adapt to the cultivation conditions of different plants.

[0037] Several parallel supplementary lights 8 are fixedly installed on the inner walls of the left and right sides of the box 1, corresponding to the height position of each bearing unit 3. The supplementary lights 8 use full-spectrum LED beads to provide suitable lighting conditions for the plants, and their on / off switch and brightness can be controlled individually.

[0038] The isolation plate 4 adopts a pull-out installation structure: several limiting grooves 42 adapted to the isolation plate 4 are symmetrically opened on the inner walls of the left and right sides of the box body 1. The limiting grooves 42 extend horizontally along the depth direction of the box body; limiting blocks 41 are fixedly installed on the left and right sides of the isolation plate 4, and the limiting blocks 41 are tightly embedded in the limiting grooves 42 and slide in cooperation with the limiting grooves 42. The side of the isolation plate 4 near the box door 2 is tightly fitted with the sealing strip 10 at the corresponding position on the inner side of the box door 2, dividing the internal cavity of the box body into multiple independent upper and lower cultivation chambers, directly blocking the vertical airflow exchange and solid heat conduction between the chambers. The operator can insert or remove the isolation plate 4 according to the cultivation needs, flexibly adjusting the number and volume of the independent chambers.

[0039] A control panel 9 is fixedly installed on the front outer surface of the enclosure 1. The control panel 9 has a built-in control unit that is electrically connected to the air box 6, the electric proportional valve 515, the first heating wire 516, the second heating wire, and the supplementary light 8. The control panel 9 is equipped with a touch screen and operation buttons, which can independently set the target temperature, air volume, illumination duration, and brightness of each chamber to achieve automated control.

[0040] Working principle: In use, according to the type, quantity and temperature requirements of the cultivated plants, insert the corresponding number of isolation plates 4 to divide the interior of the box 1 into several independent cultivation chambers; push the protrusion 77 inward to unlock the fixing component 7, push the support plate 31 carrying the plants along the slide groove 323, and after releasing the protrusion 77, the reset spring 74 drives the fixing post 73 to insert into the fixing hole 324 to complete the locking of the support plate.

[0041] The target temperature and illumination parameters for each chamber are set via control panel 9. The airbox 6 is activated, and airflow is distributed from the main air duct 514 to the first branch ducts 513 of each chamber. After entering the first air chamber 511, it is heated and regulated by the first heating wire 516, and then blown into the cultivation chamber along the side wall from the air outlet 512. After circulating evenly within the chamber, the airflow enters the second air chamber 521 from the opposite return air outlet 522, and then flows into the main return air duct 524 via the second branch duct 523, returning to the airbox 6 to form a closed-loop circulation. By adjusting the opening of the electric proportional valve 515 and the power of the heating wire in each chamber, the temperature of each chamber is precisely controlled, achieving independent temperature control for each layer.

[0042] When it is necessary to remove or place plants, pull the support plate 31 outward, and the T-shaped sliding plate 322 slides outward along the T-shaped guide rail 321. The telescopic rod 331 extends accordingly and forms a triangular support to ensure the stability of the support plate. When it is necessary to clean or replace the support plate, push the protrusion 77 inward to unlock it, and the support plate 31 can be pulled out horizontally for maintenance.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
